I am not sure, but I thought that's what i had wrong with my Xbox last month. I bought it in September, so it is pretty new. I have a Best Buy warranty that I think does cover things like this. Anyway, I did not recall the error message that came up. I was playing Rock Band and it froze in the middle of a song and one red light came on, on the bottom right. I did some research and the only thing I could find that seemed similar was this hardware failure message. I took some advice from the Xbox site and disconnected all the wires and HDD from the system, then reconnected them. It has worked fine since. I think maybe the USB cable for the RB drum set wasn't plugged in all the way, maybe? I dunno. I am just happy it works now.
